enermax 500w liberty question

[VioLent]

Just got back from microcenter and picked up a new psu for my little brother's computer. The old psu wasn't holding it. So I picked up the enermax liberty as it was recommended to me a few times. I plugged everything in and from the looks of everything it powered on fine, with the exception of the dvd-rom, that does not power on. So I figured it could be a faulty modular cable. I swap it out with another and same thing, no power for the dvd-rom. I then took a look at the psu itself and noticed there were two red plugs for PCI-E only. So my question is would my 6800GT AGP take too much amperage from one rail and cause some of my parts no to function? (e.g. dvd-rom, cpu, VIDEOCARD?)

system:
CPU: INTEL 2.8E socket 478 (very hot )
MoBo: ASUS P4P800-E DELUXE (annoying voice repeating cpu fail message)
RAM: KINGSTON Hyper-X pc-4000 2x512MB
HD: WESTERND 120G IDE
DVD/CD-ROMS: Sony DVD-R

Before coming to my question, I thought it was due to some other component in the computer, so I reseated the ram & cpu nearly 5 times! (used up all my arctic silver!!!)I then Resetted CMOS, took out the battery, re-wired all the modular cables, switched video cards, switched monitors, took some aspirin, and I even walked my dog to relieve some of the frustration

Thanks for taking your time to read all of that, I spent my whole sunday trying to get it to work and I'm in too deep :-\ Any help, ANY HELP AT ALL will be greatly aprreciated =D

its probably not from the video card because the 12v rails from the gpu are probably seperate from the rest. well at least in my psu in signature 4 x 12v, 1 for cpu, 1 for gpu, 1 for mb, 1 for 4 pin molex connectors

So it wouldn't matter if I don't used the PCI-E slots?
